Italian debut for sensor range

Schmitt Europe's range of advanced industrial laser measurement, alignment and surface roughness gauging systems are showcased in Italy for the first time at the BIAS international trade show.

Schmitt Europe's range of advanced industrial laser measurement, alignment and surface roughness gauging systems are showcased in Italy for the first time at the BIAS international trade show The company's products are being demonstrated by its newly appointed agent, Instrumentation Devices, on Stand G5-7 in Pavilion 9/1 at the exhibition, which takes place in Milan until 17th September

With applications ranging from heavy engineering, paper production and medical imaging, to micron level part and surface inspection, the rapidly expanding Schmitt range includes distance measurement equipment, laser displacement sensors and alignment systems, as well as surface roughness and scatter measurement devices.

Schmitt products on show at BIAS include AR-200 series short range sensors, AR-600 laser displacement sensors, AR-4000 distance measuring and line scanner units, as well as the company's Microscan surface roughness and scatter measurement system.

The four models in the AR-200 series cover distance measurements of up to 6, 12, 25 and 50mm, with accuracies of 12, 24, 50 and 100um, respectively.

Each unit is an ultracompact 70 x 49 x 20mm and weighs just 85g - ensuring simple installation in even restricted access applications.

The devices are ideal for use with most materials, including transparent or highly reflective surfaces, such as polished metal, water or glass.

The AR-600 family of 11 triangulating laser displacement sensors offers excellent accuracy and sensitivity.

The smallest version records distances over a measurement range of 3.2mm, with an accuracy of 4um; and the largest member in the range provides a full scale reading of 1270mm, with an accuracy of 1.27mm.

Ideal for a wide range of high speed measurement operations, including automated packaging, process control, machining and co-ordinate measurement applications, AR-600 series sensors are configurable to operate at rates from 1250 sample/s to 1 sample every 5s, as well as "on demand".

The self-contained units employ specular and diffuse reflection measurement to suit materials ranging from polished surfaces, glass and transparent liquids to molten metals and opaque solids.

Sensors also feature a background light emission mode for brightly lit areas and are equally applicable for through-window inspection of food products or hazardous materials.

Suitable for most diffuse reflective surfaces, AR-4000 optical distance sensors have an operating range from zero to 15,240mm in calibrated mode and beyond this distance uncalibrated.

An eye-safe version is also available for use with reflective tape.

With 2.54mm accuracy, 0.5mm short term repeatability, and sample rates of up to 200kHz, AR-4000 units are ideal for distance measuring applications that demand high precision and fast response rates - such as machine vision, autonomous vehicle navigation, 3D imaging, levelling and positioning operations.

The complementary AR-4000 line scanner collects and processes distance data throughout a full 360 degree sweep.

The compact and lightweight unit incorporates a balanced rotating mirror with an optical reflectance of 96%, to ensure maximum sensitivity.

It also features a motor encoder with 4096 position counts/revolution and will achieve scan rates of up to 2600 lines/minute.

Schmitt's Microscan is a simple to use, portable surface roughness, reflectance and scatter measurement instrument that enables precise measurement to be taken at remote sample locations.

With a measurement range from 1 to 1100 Angstroms, this battery operated, lightweight unit is ideal for inspecting optical surfaces, semiconductor wafers, precision machined surfaces, or rolled and formed components.

In operation, users simply place the measuring head on the surface to be inspected and press a button.

Readings take less than 5s to process and can be automatically stored in the unit's 700 capacity data memory.

In addition, the versatile Microscan can be programmed with user-definable pass/fail criteria and can be easily adapted to perform process control functions. Request free introductory details about products from Schmitt Europe ...
